leaf minerAny of various insect larvae that live and feed within a leaf, including caterpillars, sawfly larvae, beetle and weevil grubs, and dipteran maggots. Most leaf-miner burrows or tunnels are either thin, winding, whitish trails or broad, whitish or brownish blotches. Though leaf miners do not usually cause injury, they mar the appearance of ornamental trees and shrubs. One method of control is to remove and burn infested leaves; spraying with nicotine solutions or dusting with insecticides is effective only when the adults are emerging. leaf miner [′lēf ‚mīn·ər] (invertebrate zoology) Any of the larvae of various insects which burrow into and eat the parenchyma of leaves.
